'A clover, a clover of two,
Put it on your right shoe;
The first young man you meet,
In field, or lane, or street,
You shall have him,
Or one of his name.'

This, while presenting a considerable amount of uncertainty in the result has, at least, the merit of presaging something.

In other parts, however, and in more ancient days, the carrying of the four-bladed clover was believed to bring luck in play and in business, safety on a journey, and the power of detecting evil spirits. In Germany the clover was held almost sacred whenever it had two or four blades. Now, as to luck, a curious thing is stated by the author of the Plant Lore of Shakespeare. He says that clover is a corruption of clava, a club, and that to this day we preserve the emblem of luck on our playing-cards in painting the suit of clubs. Somehow the etymology does not seem very satisfying; but at any rate we all know what 'living in clover' means.

Yet, perhaps, everyone does not know that in rural districts the clover is looked upon as a capital barometer, the leaves becoming rough to the feel when a storm is impending. A writer, quoted by Mr. Thiselton-Dyer, says that when tempestuous weather is coming the clover will 'start and rise up as if it were afraid of an assault.'

It is probable that the association of good luck with the four-bladed clover arose from its fancied resemblance to the cross. Support is given to this hypothesis by the traditional origin of the shamrock as the badge of Ireland. In the account given of St. Patrick in The Book of Days, it is stated that once when the Saint wanted to illustrate the doctrine of the Trinity to his pagan hearers, he plucked a piece of the common white clover. Now, it seems that the trefoil is called shamrakh in Arabic, and was held sacred in Persia. And it is remarkable that Pliny says the trefoil is an antidote against the bites of snakes and scorpions. It is not by any means certain that the common clover was the original shamrock of Ireland; and even to this day many claim the title for the wood-sorrel. Still, for fifty years, at any rate, the popular belief has been that the trefoil-clover is the plant which was plucked by St. Patrick, who drove out the snakes from Ireland, who is still her patron-saint, and whose badge is worn to this day.

But how did the name come from Arabia, and what is the connection between Pliny's theory and the legend, of St. Patrick's victory over the vermin? These remain among the unsolved mysteries of folk-lore.

With the emblem of Scotland—the thistle—not so many classical associations and active superstitions are to be found, but yet it is not devoid of folk-lore. Of course opinions differ as to what was or is the true Scotch thistle, but of the several varieties of thistles many beliefs are entertained. One variety—the Carline—is esteemed in some parts as a barometer, as it closes up when rain is approaching. In Tartary there is a variety which grows to such a size that it is planted for shelter on the windward side of the huts on the Steppes. This thistle is called the 'Wind Witch,' because, after the heat of the summer is past, the dried portions take the form of a ball, with which the spirits are supposed to make merry in the autumnal gales.

The origin of the name thistle is probably Scandinavian, and associated with Thor. The plant was, at any rate, sacred to the Scandinavian god, and was believed by the old Vikings to receive the colour of the lightning into its blossom, which thereupon became endowed with high curative and protective virtues. There was a species of thistle on Dartmoor which used to be called Thormantle, and was used in that district as a febrifuge. Some writers have said that in Poland some infantile disorders are supposed to be the work of mischievous spirits using thistle-seed.

The Lady's Thistle, which some believe to be the true Scotch thistle, is one of the many plants associated with the Virgin. The tradition, according to Brand, is that the white spots on the leaves are due to the falling of some drops of the Holy Mother's milk, a legend we have seen to be attached also to the lily. Then the great Emperor Charlemagne's name is blended with that of the Carline Thistle, the story being that during the prevalence of an epidemic among his troops he prayed to God for help. An angel appeared, and indicated, by firing an arrow, a plant which would allay the disease. This was the Carlina acaulis, which, of course, cured all the sick soldiers, and possibly may have some of the febrifuge virtues which the Dartmoor people fancied existed in another kind of thistle. Nettle-soup is still a familiar housewife's remedy for some childish ailments.

In some parts of Germany there is a superstition that sores upon horses' backs may be cured by gathering four red thistle-blossoms before daybreak, and placing them in the form of a square upon the ground with a stone in the middle. It is not easy to trace the probable origin of this belief, but many of the old herbalists mention the thistle as efficacious in cases of vertigo, headache, jaundice, and 'infirmities of the gall.' Says one, 'It is an herb of Mars, and under the sign Aries.' Therefore, 'it strengthens the attractive faculty in man and clarifies the blood, because the one is ruled by Mars. The continual drinking the decoction of it helps red faces, tetters, and ringworms, because Mars causeth them. It helps the plague, sores, boils, itches, the bitings of mad dogs and venomous beasts, all which infirmities are under Mars.' This same writer agrees with Dioscorides that the root of a thistle carried about 'doth expel melancholy and removes all diseases connected therewith.' In other words, the thistle was held to possess all the virtues now claimed for podophyllum, blue-pill, and dandelion—a universal antibilious agent!
